Hartley, [2024] MAPA 1024\nCourt File No.: MAP-CV-88107\nDate: 2024-03-14\n\nBETWEEN:\nMARIE TREMBLAY\nAppellant\nand\nDANIEL HARTLEY\nRespondent\n\nREASONS FOR JUDGMENT\nBENNETT J.A.\n\n[1] The appellant, Marie Tremblay, appeals from an order of Blanchard J. dismissing her action for breach of a residential renovation contract. The principal issues on appeal are whether the trial judge erred in finding the contract was repudiated, and whether the mitigation credit applied against the damages award was correctly calculated.\n\n[2] The written agreement between the parties is dated February 12, 2022. Under its terms, the respondent, Daniel Hartley, agreed to renovate the appellant's principal residence in exchange for a fixed price of $94,500, with completion scheduled for June 30, 2022.\n\n[3] The trial judge found that, for reasons that were disputed at trial, the renovation was not completed by the stipulated date. The appellant vacated the premises and eventually engaged a second contractor to finish the work at a cost of $41,200.\n\n[4] In my view, the governing legal test for repudiation is whether the breaching party made it clear, by words or conduct, that it would not perform the contract according to its terms. Where the breach is anticipatory, the innocent party may treat the contract as at an end and sue immediately for damages.\n\n[5] This principle is well established and was correctly articulated by the trial judge. The key question on appeal is narrow: whether there was an evidentiary basis for her conclusion that the respondent had no intention to complete performance.\n\n[6] I am satisfied that the record amply supports that finding. The respondent's project manager communicated in writing that the crew had been reassigned to another site and that the appellant should \"plan for the fall.\" This was an express and unequivocal indication that performance would not be forthcoming.\n\n[7] The trial judge's assessment of credibility deserves deference. She observed the witnesses directly and made a considered credibility finding in favour of the appellant's account of the communications. An appellate court should not interfere with such findings absent palpable and overriding error.\n\n[8] The appellant's position on mitigation is equally sound. A plaintiff is bound to take reasonable steps to mitigate her losses, and where she does so, the breaching party bears the burden of proving that loss could have been avoided by reasonable means.\n\n[9] The second contractor's invoice of $41,200 was detailed and was not seriously challenged at trial. The trial judge correctly treated the amount as reasonable in the circumstances.\n\n[10] Accordingly, I would allow the appeal in part. The finding of repudiation is confirmed. The damages award of $94,500 is reduced to $53,300 to reflect the mitigation credit of $41,200 that ought to have been applied.\n\n[11] In the event that my conclusion on the damages calculation was doubted, I observe that the appellant also sought interest from the date of breach. That issue was not raised before the trial judge and was not argued on appeal, and I need not decide it.\n\n[12] Given the mixed result, I would award the appellant her costs before this court, fixed in the amount of $4,800, payable by the respondent. I would make no order as to costs below.\n\nDATED at Mapleford this 14th day of March, 2024.\nBENNETT J.A.\n`;\n","createdAt",["D",1788720422688],"branchVersion","branchId","9da8d75d-5b67-4db9-bfe9-96a9f922df07","id","98a438e2-e86c-4387-8e64-73a6f374b982","caselens-canada",["D",1788720339103],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","Canadian judgment analyzer, highlights citation-worthy passages","imageUrl","436e5f36-a2ba-4a6a-a643-a30cb32bc6d0","pinnedFileId","01a0780a-5903-77b6-aac8-7b10e8bcd475","pinPreview",true,"pinMigrated","screenshotVersion","likeCount",0,"orgId","01a07805-dad2-708b-ba9b-d68c374aef77","tursoName","98a438e2e86c43878e6473a6f374b982","tursoHostname","98a438e2e86c43878e6473a6f374b982-val-town.aws-us-east-2.turso.io","tursoMeasuredAt",["D",1789504908499],"pinned","userPerm","r","valPerm","blobPerm","rw","emailPerm","sqlitePerm","projectPerm","telemetryPerm","user",{"_105":104,"_113":109},"org",{"_105":104,"_106":107,"_108":109,"_19":60,"_110":111,"_112":30},"branch",{"_13":94,"_37":95,"_48":47,"_96":49,"_97":-5,"_98":-5,"_99":-5,"_100":-5,"_101":-5,"_102":50,"_103":104},"isOwned",28,"main","projectId","forkedBranchId","forkedBranchVersion","forkedProjectPrivacy","forkedProjectId","forkedProjectOrgId","projectName","userHandle","justinstevens","handle","displayName","Justin Stevens","avatar","https://lh3.googleusercontent.com/a/ACg8ocKLKYD-xizVJxt8-uDEezaNk_hNn0G1pUiiV0LSrwEU1mcm1qa4=s96-c","tier","free","canRestrictVals","profileImageUrl","branchName","","adoptOrgId",{"_48":49,"_37":50,"_43":268,"_52":-5,"_53":30,"_54":55,"_56":55,"_57":58,"_59":-5,"_19":60,"_61":62,"_63":64,"_65":-5,"_66":-5,"_67":68,"_69":70,"_71":72,"_73":74,"_75":269,"_77":-5,"_78":79,"_80":79,"_81":82,"_83":82,"_84":82,"_85":79,"_86":79,"_87":270,"_89":271,"_91":272,"_93":30},"tree",[186,195,196,197,198],"files",[186,187,188,189,190,191,192,193,194,195,196,197,198],"counts",{"_176":68,"_177":153,"_178":68,"_179":180,"_181":182},"contents",[136,137,138,139,140],"upstreamProject","upstreamBranch","emptyEnvVars","flags",[],"hasHttpFiles","grants","orgs","customDomains",{},{"_48":170,"_37":171,"_35":172,"_144":-5,"_46":47,"_45":153,"_146":64,"_43":173,"_13":68,"_39":174,"_41":-5,"_29":30,"_149":-5,"_32":175},{"_48":164,"_37":165,"_35":166,"_144":-5,"_46":47,"_45":153,"_146":64,"_43":167,"_13":68,"_39":26,"_41":168,"_29":30,"_149":-5,"_32":169},{"_48":158,"_37":159,"_35":160,"_144":-5,"_46":47,"_45":153,"_146":30,"_43":161,"_13":68,"_39":26,"_41":162,"_29":30,"_149":-5,"_32":163},{"_48":151,"_37":152,"_35":62,"_144":-5,"_46":47,"_45":153,"_146":30,"_43":154,"_13":68,"_39":155,"_41":156,"_29":30,"_149":-5,"_32":157},{"_48":141,"_37":142,"_35":143,"_144":-5,"_46":47,"_45":145,"_146":64,"_43":147,"_13":68,"_39":40,"_41":148,"_29":30,"_149":-5,"_32":150},"9b30d97f-8b98-4c48-9a4d-868ad6d9c5e0","types.ts","49c0a90e-aa23-11f1-8352-1607ee4eb77e","parentId",2,"latest",["D",1788720396299],"/**\n * Shared types for CaseLens Canada — used by both the server pipeline\n * (server/*.ts) and the client SPA (frontend/**).\n */\n\nexport type CategoryKey =\n | \"ratio\"\n | \"rule\"\n | \"application\"\n | \"fact\"\n | \"credibility\"\n | \"procedural\"\n | \"remedy\"\n | \"obiter\"\n | \"definition\";\n\nexport interface LegendEntry {\n key: CategoryKey;\n label: string;\n short: string;\n /** what a lawyer typically calls this kind of passage */\n explanation?: string;\n bg: string;

Click **Remix** to get your own copy.\n\n## Picking a starter\n\n| Starter | When to pick it |\n| --- | --- |\n| [`basic-html-starter`](https://www.val.town/x/templates/basic-html-starter) | Static HTML pages. Sprinkle of vanilla JS. No server-side rendering. |\n| [`hono-jsx-starter`](https://www.val.town/x/templates/hono-jsx-starter) | Dynamic server-rendered HTML with JSX. API routes. No React, no SPA. |\n| **[`react-hono-starter`](https://www.val.town/x/templates/react-hono-starter)** *(you're here)* | Client-side React SPA with a Hono API backend. |\n\n**Want to build UI?** Start writing React components in\n[`frontend/components/`](/frontend/components/). Import them into `App.tsx` and\nyou're good to go. Styling is [Twind](https://twind.style/) — just use Tailwind\nutility classes, zero config.\n\n**Want to add an API?** Add routes in [`index.ts`](/index.ts) (there's a\ncommented-out example). Fetch them from your React components.\n\n## Architecture\n\n```mermaid\ngraph LR\n Browser -->|\"GET /\"| Hono[\"index.ts
(Hono server)\"]\n Hono -->|serves| HTML[\"root.tsx\"]\n HTML -->|loads| Entry[\"index.tsx\"]\n Entry -->|renders| App[\"App.tsx\"]\n App -->|renders| Counter[\"Counter.tsx\"]\n```\n\n## File structure\n\n```\nindex.ts ← Hono backend (serves frontend + API routes)\nfrontend/\n root.tsx ← HTML shell (stamps immutable asset URLs)\n index.tsx ← React entrypoint (mounts )\n favicon.svg ← App icon\n components/\n App.tsx ← Root component (layout + view source link)\n Counter.tsx ← Example component with state\n```\n\n## How it works\n\n1. **`index.ts`** is the HTTP entrypoint — a Hono server that serves the\n frontend and any API routes you add.\n2. **`frontend/root.tsx`** is the HTML shell — it loads Twind and stamps\n immutable asset URLs for the favicon and React entrypoint.\n3. **`frontend/index.tsx`** mounts the React app.\n4. **`frontend/components/App.tsx`** is the root layout — add new components\n alongside it.\n5. **`frontend/components/Counter.tsx`** is an example stateful component —\n replace it with your own!\n\n## Next steps\n\n- Add API routes in `index.ts`\n- Add new components in `frontend/components/`\n- Add a SQLite database — see the\n [React Hono Example](https://www.val.town/x/stevekrouse/reactHonoExample) for\n a full-stack example with database, queries, and shared types\n\nTemplate updates and upgrade paths for existing remixes: [CHANGELOG.md](/CHANGELOG.md)\n",[159],"3ba147c7-9d07-4444-9b21-71b45cae8c00","CHANGELOG.md","01a0780a-5903-77b6-aac8-70166b5b6141",["D",1788720339103],"# Changelog\n\n## 2026-07-30 — Immutable asset caching\n\nFrontend files are now served at version-addressed URLs\n(`/__immutable/45/frontend/index.tsx`) with\n`Cache-Control: public, max-age=31536000, immutable`, so repeat visits load the\nwhole client graph from the browser cache — roughly 3× faster (~665ms → ~157ms\nmeasured). Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1. Create `frontend/root.tsx`:\n\n```tsx\n/** @jsxImportSource npm:hono@4/jsx */\nimport { raw } from \"npm:hono@4/html\";\nimport { immutableFileUrl } from \"https://esm.town/v/std/utils/index.ts\";\n\n// The HTML shell for the app. It is never cached, so immutableFileUrl can stamp\n// the current val version into each asset URL — the browser caches those\n// immutably, and publishing the val changes the URLs, refetching exactly once.\nexport function Root() {\n return (\n <>\n {raw(\"<!DOCTYPE html>\")}\n <html lang=\"en\">\n <head>\n <meta charSet=\"UTF-8\" />\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" />\n <title>React Hono Val Town Starter\n
